What causes the water in the oceans to be salty?

Salts are minerals that are dissolved from rocks and soils during erosion.  Freshwater is actually a misnomer- all surface waters contain some concentration of salts.  While concentrations are low in flowing waters-- in oceans (and some landlocked lakes, like the Great Salt Lake) there are no outlets, so the salts are concentrated as water evaporates.
